The launch of the Geostationary Operational Environmental Satellite (GOES-N) aboard a Boeing [NYSE:BA] Delta IV rocket was scrubbed this evening.
Following a temporary hold in the countdown, the count resumed and the launch team transferred power from ground support equipment to launch vehicle internal power. During this activity, the telemetry engineer observed a red alarm and called a hold when the auto system monitoring battery voltage on the launch vehicle's second stage determined that the voltage did not transition within the predicted time period.
Engineers are investigating the situation to determine why the system exceeded limits and what adjustments need to be made prior to the next launch attempt.
Boeing is unable to determine a new launch date at this time. The flight termination system batteries on the vehicle have now exceeded their demonstrated test life, and Boeing does not have the ability to install new batteries in time for an attempt prior to the eclipse period.
Further updates will be provided on the Boeing Launch Hotline (714) 896-4770.
